Abstract: The nutritional compositions of 21 germplasm resources of seleng wormwood（Artemisia selengensis Turcz.） were determined and evaluated. The results showed that, the dry matter content, the protein content, the total sugar content and the crude fiber content of the 21 seleng wormwood were 6.69%~11.18%, 1.27%~2.00%, 0.39%~2.52% and 0.90%~1.60% respectively. The seleng wormwood of Xiaoyehong had the highest dry matter content, total sugar content and crude fiber content; and the seleng wormwood of Xishanqu had the highest protein content in 21 accessions. The dry matter content of seleng wormwood was extremely significant positive correlation with the total sugar content. Compared with over 30 green leafy vegetables, seleng worwood had higher dry matter content, crude fiber content and lower protein content.

Key words: seleng wormwood（Artemisia selengensis Turcz.）, germplasm resources, nutritional composition, evalution
